A luminaire includes a radio wave sensor, a luminaire body and a cover. The radio wave sensor is configured to detect, using radio waves, movement of an object within a detection area by a Doppler Effect due to the movement of the object. The luminaire body holds the radio wave sensor. The cover is attached to the luminaire body and covers the radio wave sensor, the cover allowing the radio waves to pass through. The radio wave sensor includes an antenna for transmitting/receiving the radio waves. An antenna face (receiving surface) of the antenna for receiving the radio waves is inclined relative to the cover.

A sensor protection apparatus includes a first sensor cover movable between a sensor covering position and a first cover waiting position; a second sensor cover movable between the sensor covering position and a second cover waiting position, wherein each of the first and second sensor covers is located at the sensor covering position for protecting the surface of the sensor from being contaminated by foreign matter; and an actuator configured to move the first and second sensor covers such that the first sensor cover and the second sensor cover are alternately located at the sensor covering positions thereof.

A sensor mounting system that includes a sensor, a mounting ring, a faceplate support, and a faceplate. The mounting ring includes a first opening and a first plurality of threads that are disposed on an interior surface of the first opening. The faceplate support is disposed within the first opening of the mounting ring. The faceplate support includes a second plurality of threads that are configured to engage the first plurality of threads of the mounting ring and a second opening. The faceplate is disposed within the second opening of the faceplate support. The faceplate is coupled to the sensor and is configured to rotate within the second opening of the faceplate support.

A first step sets a second inclination angle of a housing to an angle different from a reference housing angle by a limit angle; drives an actuator to set a first inclination angle to an angle different from a substrate inclination angle by the limit angle such that a beam axis is kept to be oriented to a specified direction; and measures, based on transmission and reception of a radar beam, first received power. A second step drives the actuator to set the first inclination angle to an angle located outside the adjustment range by a predetermined additional angle while the first inclination angle is maintained; and measures, based on transmission and reception of the radar beam, second received power. A third step determines whether a difference between the first received power and the second received power is greater than a predetermined determination threshold, and checks an operating state of the actuator based on a result of the determination.

A heater for vehicular sensors is configured to pass sensing energy and thereby permit placement of the heater directly over the sensing area in the path of the sensed energy. In this way, direct heating of the sensing area is provided minimizing the energy necessary to prevent icing and improving deicing speed.

A radio detection and ranging (radar) apparatus may include an antenna including a plate-shaped circuit board having one surface provided with a first element and a second element mounted thereon to transmit or receive radio waves, a radome configured to cover the one surface of the circuit board and including a protrusion protruding from an inner surface thereof at a side towards the circuit board, a shield configured to cover the first element and including a coupler that is detachably coupled to the protrusion, and a case coupled to the radome to cover the other surface of the circuit board.

A transmission module includes n oscillator modules and a phase command signal generator. Each of the oscillator modules includes a voltage controlled oscillator and an amplification circuit. The voltage controlled oscillators output transmission high-frequency signals having the same frequency and synchronized among the n oscillator modules by synchronous control based on a common reference signal. The amplification circuits each perform power amplification for the transmission high-frequency signal from a corresponding one of the voltage controlled oscillators and output the resultant signal. Phases of the transmission high-frequency signals synchronized among the n oscillator modules and output from the voltage controlled oscillators are separately controlled according to respective n phase command signals from the phase command signal generator.
